The river rises on Dduallt in Snowdonia and flows east through Bala Lake, Corwen, and Llangollen. It turns north near Overton-on-Dee and forms part of the England–Wales border before fully entering England north-east of Wrexham. It flows through Chester then re-enters Wales; the final section is canalised and discharges to the Irish Sea via an estuary 23 km (14 miles) long.
